Super Loop Antenna
The Superloop is the 30' length of ladderline hanging down from the center insulator. This length has been tuned so that appears to be a open circuit stub on 40 meters; thus the antenna becomes two full wave wires at 40 meters and is commonly referred to as the Bi Square antenna
The 40/30 Pyramid
I have something here that I believe is new. If it isn't then that's ok ,I don't use EZNEC or read antenna articles much. I like to innovate. This antenna is an innovation. I have read about a sloping two band Delta loop but it used two feed lines mine uses one. It is called the 40/30 pyramid
Two element parasitic delta loop array
Ladder line fed loops perform well.K4QKY hasbeen using large multi band ladder line fed loop antennas with good success for many years

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
